Procedure for making the surgical device in case 2. a The right and left mandibular rami of the 3D model were connected by an autopolymer resin to keep the preoperative position between proximal and distal segments. b Based on the findings in a CT image, the range of resection was determined and segmental resection was performed on the 3D model. The reconstruction titanium plate was bent, and the positions of the plate and holes were marked on the 3D model. c The device was made to fit the lower border of the anterior mandible and the posterior border of the mandibular ramus. The surgical device to guide the direction of mandibular resection (dotted line) had a U-shaped handle so that adaptation of the device would not interfere with the soft tissue to be removed and had holes (arrow) to be fixed on the mandible with screws
